VENTILATING AND AIR-COOLlNG MECHANISM.

SPECIFICATION forming part Of Letters Patent No. 787,454, dated April. 18, 190 5. I

Application filed June 14, 1904.- Serial No. 212,575.

To rtll whom it may concern: I Be it known that I, JAMES KELLY, a citizen of the United States, residing at the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Air-Cooling Apparatus, of which the following is a specification.

My invention relates to means of ventilating and cooling the air of apartments and buildings, and is especially adapted for use in cotton-mills and other factories where the air. is liable to become very dry or full of dust of fibers in consequence of the operation of machinery or the employment of manufacturing processes, which are detrimental to the health or comfort of the workmen; and said invention consists of the novel construction and combination of the several parts, as hereinaf-v ter described, and specifically set forth in the claims.

Figure 1 is a side elevation of my improved air-cooling apparatus. Fig. 2 is a View, partly in elevation and partly in section on line X X of Fig. 1, of the fan, its driving mechanism, the case, and the water-spraying devices. Fig. 3 'is a front elevation of the water pipe and sprayer. Fig. 4 is a view of the same as seen on line Y Y of Fig. 3. Fig. 5 is a view in central longitudinal vertical section of the separator constituting a part of my said inven- Fig. 6 is a transverse section as seen on line Z Z of Fig. 5. Fig. 7 is a top plan view of the vapor-distributer. Fig. 8 is a view of the same as seen in diametrical section.

Like numerals indicate like parts.

In the drawings the said apparatus is supported by the hangers 1, 2, 3, 4, and 5 from the beam or ceiling 6, said hangers being fastened in position by the headed bolts 7, 8, 9, 10, and 11. The hangers 1 and 2 support the fan-case 12, which, as shown in Fig. 2, is preferably made in two halves or sections, each having circumferential flanges which are fastened together at intervals by bolts 13.

Tire case 12 has a centrally-located hub or bearing 14, in which is jouinaled the shaft 15. The opposite end of the shaft 15 is journaled in the bearing16 of the hanger 5. On said end of the shaft 15 is a collar 17, held to said shaft by a set-screw 18. At the forward end of the shaft 15 is mounted a fan 19. A pulley 20 is mounted fast on the shaft 15 and is driven by a belt 21 from a shaft rotated by power.

The fan-case 12 has a funnel or air-inlet 22, and at or near the bottom is also an outletpipe 23. sure throughthe pipe 24, which is provided witha valve 25. nected by an elbow 26 with a vertical pipe 27. The pipe 27 enters the inlet 28 of the spraypipe 29. This spray-pipe is a ring or circular tube having a number of small discharging holes ororifices 30 on the inner side thereof. As shown in Fig. 2, this ring or spray-pipe 29 is placed within the funnel or air-inlet 22 of the fan-case 12, with its discharge-orifices diverted inwardly toward the fan 19.

A cylindrical separator 31 is held by the hangers 9 and 10. These hangers have flanges 32 and 33. The separator 31 has tangentiallyextending flanges 34 and 35. 'Thesefianges 32, 33, 34, and 35 are fastened together by bolts 36 37, as seen in Figs. 1 and 6.

The separator 31 has annular flanges 38 and 39 atits ends, as shown in Fig. 5. At each end of the separator 31 is a head 40. Each head 40 has an inner annular lip 41 and a central hub 42, whose boreis screw-threaded. The flanges 38 39 are fastened by bolts 43 to'the heads 40, respectively. The annular lips 41 fit in the bore of the separator 31, as 'seen in Fig. 5.

A pipe 44 fits in the outer end of the pipe 23 and screws into the hub 42 of the separator 31.

In the separator 31 is loosely mounted the collar 45, which has a concentric annular flange of less diameter andwhose outer edge lies against the inner side of one of the heads 40, as seen in Fig. 5. The opposite face of said collar 45 has two concentric grooves, one having a larger diameter than the other.

A deflector 46, having its exterior surface somewhatconical in form, as shown in Fig. 5,

is supported concentrically in the separator 31 by braces 47, and its inner annular edge has two concentric gr oves of the same diameters, respectively, as those of the grooves o" the collar 45.

Cold water is conveyed under pres- The water-pipe 24 is con- Into the smaller of these :ur

, fan discha nular grooves in both the deflector and the collar is mounted a cylindrically-hent sheet of fine wire-gauze, as indicated at 4-8 in Figs. 5 and 6. A layer or packing of pieces of sponge i9 is placed on the wire-gauze cyiinder i8, and another cylindrically-hent sheet of line wire'gauze is mounted in the larger of the annular grooves of the collar 45 and deflector i6.

A pipe 51 is screwed into the huh of the head to, which is nearest the collar is, and is connected at its opposite end by the elbow 52 to the pipe 53. The pipe 53 has a valve Set. A circular vapor-distributor is screwed upon the bottom of the pipe 53 and has a number of holes 56, through which the vapor is discharged, as represented in Fig. i.

The separator 31 has a tube 57, which is screw-threaded inside, and a drip-pipe 58 is inserted in said tube. The drip-pipe 58 has a valve 59.

The operation of my said air-cooling apparratus is as follows: Power applied by the oelt 21 rotates the puiley 2G and the shaft 15, on which said pulley is fastened. The shaft 15 rotates the fan 19-, which fastened thereen, in such direction as to create a suction or air through the funnel or air-inlet as indicated by the arrows at a: Fig. Cold water under pressure flows through the pipe 24: when the vaive 25 is open and aence passes through the elbow 26, pipes Q? and the circular spray-pipe or ring 29, whence it is discharged in small jets, as indicated oy line arrows Z) i) in Fig. 92, directly against the vanes oi the fan 19. The rapid revolution of this fan breaks these jets of cold water into fine spray, and the centrii'ugai power of the i es the spray from the is is of the vanes against the inner circumierc me of the case 12.. 'lhe mingled air and watez the case 12 is forced o the fan 19 out through the i cs 23 and eteinto the separator 31, indicated by the arrows c, Fig. 1, a, Fig. 5, and strii ing against the conicai point of the deflector d6 is divided and directed into the annular space between the inner cylindrical surface of the separator 31 and the cylinder 50 of wiregauze, indicatedin hy the arrowsf'g. The moisture-laden air then passes through the wire-gauze cylinder 50 and through the layers or packing of sponge 4:9 and through the wire-ganze cylinder 4:8, as indicated by the arrows it and 'i in in passing through the sponge layers e9 any eircess or moisture is absorbed hy the sponges, the pipe 58'when the valve 59 is open showing any accumulation of water to drip away separator, indicated by the arrow From the wiregauze cysinder and moistened air passes as indie arrows Ii' 1, out throng collar elbow 52, and pipe 53 and when the valve 5a is open into and through the distributer 55, whence it is discharged through the openings 56. For the direction of these currents see arrows m, n, and 0 in Figs. 1 and 5.

instead of sponges any other material may he used which is suihciently porous or permeable.

1 claim as a novel and useful invention and desire to secure by Letters Patent 1. in an air-cooling apparatus having a power-driven fan, a case wherein said tan is mounted and said case provided with an airinlet, a pipe arranged to spray water in front of the inlet of said case and upon the blades of said fan, and an outlet-pipe from the bottom of said case, the combination therewith, of a separator, consisting of a cylinder mou nted on proper supports; a collar mounted within said cylinder and provided with two concentric grooves; a conicaldefiector concentrically mounted on supports within said cylinder and provided with two concen tric grooves; two cylindrical-shaped sheets oi tine wire-gauze whose ends are mounted in the grooves of said collar and saiddeiiector; a layer of porous material interposed hetween the wire-gauze; ahead secured upon and closing one end of said cylinder and having" a central annular flange for connecting thereto the end of said outlet-pipe;
